Re: Mars observation filters: Do they work?

Do those Mars observation filters work? I'm thinking about the one
sold by Orion Telescope and I think Televue has one as well. Do they
make a difference? Any advice on whose to buy?


A woman in our club has tried a Sirius Planetary Contrast filter on Mars,
and she and the few others (not me) who observed with it were not impressed.
I and others I observe with have always found a Wratten #85 (salmon) filter
to work very well on Mars, and other colors are also effective on bringing
out different kinds of detail. However, the filters aren't magical and don't
make a bad view good.
